MACHINE FOR FORMING VENEER DRUMS.

SPECIFICATION forming part of Letters Patent No. 360,344, dated March29, 1887.

Application filed September 16, 1886. Serial X0. $3,654. (No model.)

To all whom it may concern:

Be it known that we, WILsoN GODFREY and GEORGE \V. HALSTEAD, both of thecity of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Machine for Forming Veneer Drums, ofwhichthe following is a full, clear, and exact description.

The object of our invention is to facilitate the manufacture of the socalled veneer drums, which are subsequently provided with heads to formpackages used principally for various kinds of dry groceries.

These drums are usually made threeply of three sheets of veneer gluedtogether, the grain of the central sheet crossing the grain of the twoother sheets, so the drum will not split or crack; and our process isfirst to glue the three sheets of veneer together and then turn themover a former and unite the edges;

. and in our process we compress the sheets of veneer upon the formerwhile the glue is moist, and thus cause the sheets to be perfectl yunited in the act or operation of bending them to cylindrical form, sothat when the glue sets and becomes dry the sheets will not cleave apartat any portion of the drum, and the machine is constructed to enable thelapped edges of the sheets, when turned to form a cylinder, to beclamped firmly by a suitable clamping device, and then withdrawn fromthe iblllllng-Cylillder, ready to receive the heads and hoops tocomplete the package.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures. Figure 1 is a plan view of theforming-cylinder, showing the passage formed therein to receive theclamping device, a part of the oylinder being broken away to show theflange at the ends, and this figure shows also a part of the table atthe end or edge of which theformingcylinder is held. Fig. 2 is an endview of the same, showing the sheets of veneer placed upon the table andone edge attached to the forming-cylinder, and the latter given aone'quarter turn from the position shown in Fig. 1. Fig. 3 is a similarview showing a clamp applied to the cylinder for holding the veneerfirmly thereon.

Fig. 4. is alsoasimilar view showing the weighted arm or compressingdevice for compressing the sheets ot'veneer upon the formingcylinder.Fig. 5 is an end elevation showingthe forming-cylinderturned to lap theedges of the veneer and two clamps applied for holding the veneer, thecompressing device being shown upon the veneer in full lines andelevated in dotted lines. Fig. 6 is a. broken end elevation showingtheclamping device applied to the lapped edges or joint of the drum, readyto remove the same from the forl'ning-cylinder. Fig. 7 is an end View ofthe veneer drum with clamping-bars attached and removed from theforming-cylinder, and provided with a false head inserted in the drum toprevent warping. Fig. 8 is a longitudinal sectional elevation of thedrum and clamping device removed from the forming-cylinder. Fig. 9 is asectional front elevation of the forming-cylinder, showing theclampingbar L secured upon the veneer and to the end flanges, a, of thesaid forming-cylinder.

A represents the formingcylinder. This is formed at its ends with theflanges a, and has the longitudinal passage A formed in it, and issecured upon the crank-shaft B, which is journaled in bearings formed inand upon the supports B B, adjacent to the table 0. The longitudinalpassage A in the forming-cylinder is made dovetailed to receive theclamp ing-bar D, and to hold it when shoved endwise into said passageagainst any material outward movement away from the axis of thecylinder.

In the recess A is pivoted the frame E, for holding the ends of thesheets F of veneer at the outset of forming the drum. The frame Econsists ofthe two side pieces, 6 e, pivoted to the ends of the cylinderA and the cross rod e, secured in the outer ends of the side pieces, 6e. The side pieces, 0 c, are hinged at the bottom of the recess A,andare of such length as to hold the bar e slightly beyond the circle orcurve described by the periphery of the forming-cylinder, so that theends of the veneer may be placed under it, as shown in the drawings. Aslot, 0, is formed in the bottom of the recess A, to receive the rod e,so that the whole frame E may be turned down below the bottom of thepassage A, as shown in Figs. 2

and 3, so that said frameiwill not interfere with the clan1ping-barD"when shoved endwise into the recess A.

The clamping-bar D is made to fit the recess A with beveled side edges,and is slightly rounded at its outer surface to correspond with theradius of the cylinder A, and is formed with a notch, a, at each end toretain the headed bolts (1, passed through the outer clamping-bar, D.(Shown in Figs. 6, 7, and 8.) The outer clamping-bar, D, is providedwith the screw cl, and when united to the barD by the bolts d d anintermediate bar, D, is placed between the bars D D upon the ends of theveneer F, so that when the screw (1 is turned down the said bars D Dwill clamp tightly upon the ends of the veneer.

G represents the device or arm for pressing the sheets of veneer uponeach other and upon the forming-cylinder A, so that they will be gluedtogether at all points, and will accurately take the form of thecylinder as the same is slowly turned by the crank B. The arm G ishinged at g to a suitable support, H, so that it may be raised by a ropeandpulleys, J J, or other means, to a position above theforming-cylinder, as shown in dotted lines in Fig. 5, or lowered to restupon the formingcylinder, as shownin full lines in Figs. 4 and 5. Thearm G is of considerable weight, and it is provided with the heavyroller G, which runs uponflthe veneer, and a brake, G", is arranged tobe pressed by screws K, against the roller G, so'that the friction ofthe roller G upon the veneer may be regulated, and so that the rollermay be made to wholly slide upon the veneer, if desired.

In forming a three-ply drum three sheets of veneer are coated properlywith glue, and placed together upon the table 0 with the edge of themiddle sheet drawn back a short distance from the edge of the bottomsheet, and the edge of the outer sheet drawn back from the middle sheet,and the edges adjacent to the cylinder A are placed under the cross-barc of the frame E, the said frame having been previously turned to radialpo sition, as shown in Figs. 2, 3, and 4. The cylinder A will then beturned by the crank B ashort distance to curve somewhat the edges ofthe'sheets of veneer, as shown in Fig. 2. Then a clamp, L, is applied tothe veneer and drum, the same being held by hook-screwslat the ends ofthe clamp engaging with the flanges a at the ends of the cylinder. Thisclamp L being applied, the arm G is lowered upon the veneer, as shown inFig. 4. Then the cylinder A is turned by crank B nearly a completerevolution, which causes the veneer to be wrapped completely around thecylinder and the sheets to be compressed snugly together. At this timeone edge of the sheets of veneer will be held by the clamp L, while theother edge will be held by the weight of the compressing device G. Thenanother clamp, L, is applied to 'the cylinder and veneer, the same beingheld by hooked bolts Z, applied to the flanges a, of the cylinder, asshown in Fig. 5. The two clamps L L being thus applied to hold the edgesof the veneer to the cylinder A, the arm G will be raised off from theveneerand the frame E turned down into the recess 0, as shown in dottedlines in Figs. 5 and 6, and then the clampbar D will be shoved endwiseinto the recess A. The opposite edges of the several sheets of veneerwill then be properly lapped upon each other to form the joint, and thenthe clamp-bars D D will be applied and the screw d turned down to firmlysecure the lapped edges of the veneer,aii d then,finally,the clamps LLwill be removed, and the drum and clamps D D D" drawn off together fromthe formingcylinder for further treatment (to receive the heads, hoops,&c.,) to form the drum into a complete package. In this mannerthe drumsmay be very expeditiously made and the joint easily formed and secured,and the sheets of.

veneer being compressed make the package very strong and durable.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The forming-cylinder A, formed with a recess, A,and provided with aretaining-frame, E, composed of side pieces and a cross-piece, the sidepieces being hinged at the bottom of the recess, in combination with theclamping bar D, substantially as described.

2. The forming-cylinder A, formed with the recess A, in combination withthe bar D and the outer bars, D .D bolts (7, and screw (1',substantially as described.

3. The cylindrical former A and devices for clamping and holding theveneer thereto, in combination with the compressing device G, hinged toa suitable support and provided with a roller, G, and brake G arrangedto be ap plied to the roller, substantially as and forthe purposesdescribed.
